Air pollution and sulphur emissions are causes of acid rain and humidity which are working abrasively and could be responsible for concrete corrosion. ConcreCem is not only a superior solution for repairing older and damaged concrete structures it is also a superior product to protect new concrete structures under various types of chemically aggressive environments whilst withstanding heavy physical and mechanical challenges.
11.4 Concrete slab South Africa
A company in South Africa requested PowerCem Southern Africa a solution for a concrete floor, without joints, and applied on a average bearing layer. A concrete slab of 375 m2 was applied with traditional concrete modified with ConcreCem. ConcreCem is used to significantly enhance the physical and mechanical properties of the monolith structure. ConcreCem also contributes to more flexibility and a faster binding process.
The Slab with a thickness of 200 mm was applied on a granular foundation that was directly applied on the black cotton clay soil. The slab has no reinforcement and no expansion joints. After 4 months of intensive mechanical use the flexible concrete layer is in great shape! In the mixture 300 kg Cement and 2,1 kg ConcreCem were used per 1 cubic meter of concrete with a water/cement ratio of 0,55.
